Overview of Samsung M393A4K40CB1-CRC DDR4 2400MT/s Ram

The Samsung M393A4K40CB1-CRC 32GB DDR4 PC4-19200 ECC Registered RAM represents a critical component within the enterprise server memory ecosystem, designed specifically to support reliability, scalability, and sustained performance in professional computing environments. Built on Samsung’s advanced DRAM manufacturing technology, this module is engineered to meet the demanding requirements of data centers, virtualization platforms, cloud infrastructures, enterprise databases, and mission-critical server workloads. The DDR4 registered architecture ensures improved signal integrity and electrical stability, making it suitable for multi-DIMM server configurations where standard unbuffered memory would fail to maintain consistency.

32GB High-Density Capacity for Scalable Server Deployments

The 32GB capacity of the Samsung M393A4K40CB1-CRC DDR4 RAM module is particularly well suited for modern server environments that demand increased memory density to support consolidation, virtualization, and data-intensive applications. As enterprises migrate toward fewer physical servers running multiple virtual machines or containers, high-capacity memory modules become essential to ensure optimal resource allocation and performance consistency. This module allows system administrators to scale memory capacity efficiently without excessive slot consumption.

DDR4 PC4-19200 Performance Characteristics

The PC4-19200 designation corresponds to a theoretical peak bandwidth of 19.2GB/s per module, providing a robust data transfer pipeline for enterprise workloads. Operating at 2400MT/s, this Samsung DDR4 module strikes a balance between bandwidth efficiency and power consumption, making it suitable for servers that operate continuously under heavy utilization. The DDR4 standard introduces architectural improvements over previous DDR3 generations, including increased bank groups, improved burst length, and reduced operating voltage.

CL17 Latency for Server Workloads

With a CAS latency rating of CL17, this memory module is optimized to deliver predictable response times suitable for enterprise applications. While server memory prioritizes stability and reliability over ultra-low latency, the CL17 specification ensures efficient command execution cycles within the DDR4 framework. This latency profile is well matched to the 2400MT/s operating speed, enabling balanced read and write operations across diverse workloads. Latency consistency is critical for transactional systems, database servers, and virtualized environments where multiple processes compete for memory access.

ECC Registered Memory for Data Integrity

Error Correcting Code functionality is a defining feature of the Samsung M393A4K40CB1-CRC memory module, providing essential protection against data corruption in mission-critical systems. ECC memory automatically detects and corrects single-bit errors while identifying multi-bit errors, ensuring data integrity during processing and storage operations. In enterprise environments where data accuracy is paramount, ECC memory is not optional but a foundational requirement. ECC registered memory plays a vital role in preventing system crashes, application failures, and silent data corruption that could otherwise compromise business operations.

Reliability for 24/7 Continuous Operation

The Samsung M393A4K40CB1-CRC is engineered for continuous 24/7 operation, making it suitable for servers that must remain online without interruption. Enterprise servers often operate under constant workloads, and memory reliability directly impacts system uptime. Samsung’s rigorous testing and validation processes ensure that this DDR4 module meets strict enterprise standards for endurance and error tolerance. This reliability is especially important in environments such as financial services, healthcare systems, telecommunications infrastructure, and cloud service providers, where downtime can result in significant operational and financial consequences.

288-Pin RDIMM Form Factor

The 288-pin registered DIMM form factor of the Samsung M393A4K40CB1-CRC ensures compatibility with a wide range of modern server motherboards and platforms that support DDR4 RDIMM memory.
